Tim Gunn Gives BIGGEST LOSER Finalists Makeovers, 5/3

It's one of the most eagerly anticipated episodes of the "Biggest Loser" season - the makeover episode! And this time, "The Biggest Loser: Couples" is joining forces with fashion icon Tim Gunn and top celebrity hairstylist Ken Paves to give fairytale makeovers to the remaining five contestants on a must-see, emotional episode airing Tuesday, May 3 (8-9 p.m. ET) on NBC.

The first wish he grants is makeovers for all, so Tim works his fashion magic by helping each of them select stylish attire to flatter their new slimmer selves. Then the contestants head to the salon of sought-after Hollywood hairdresser Ken Paves, who has crafted hairstyles for Jennifer Lopez, Eva Longoria, Lady Ga Ga, Celine Dion, Fergie, Jessica and Ashlee Simpson, and many more. He creates amazing new looks for each of the contestants, and then they're off to a spectacular evening at a beautiful Hollywood castle. Each contestant arrives by horse-drawn carriage, and is greeted by Tim, after which they get their second wish - heartwarming reunions with loved ones flown in to celebrate their big night. After emotional reunions with family members - including one who has his own amazing surprise for one of the contestants -- they are all treated to a special private concert by the popular band OneRepublic.

The magic continues at this week's challenge, which finds contestants searching through 50 car-shaped sand castles for the keys to two incredible prizes - brand new Mazda 5s. Then it's time for the weigh-in, where one final makeover surprise awaits the contestants, as well as an unexpected treat from one of the players.
